DON'T UPGRADE TO MOJAVE JUST YET...
Unfortunately we have found an issue in the public release of Mojave that was not in the Beta.
This change means that Hindenburg is not being allowed to access your audio inputs, so you will not be able to record.
We are working on a solution and will keep you posted.
If you are on High Sierra, please don't upgrade to version 1.80 - a bug on our part has created issues for some input devices.
If you have upgraded to 1.80 on High Sierra, you can downgrade here
We will fix that at the same time as we address the bug on Mojave, hopefully by Thursday 27th September.
